Dolichoderus HNS Lund.

This genus has been accepted as containing several subgenera but it appears that generic rank is indicated for certain of these. In the New World, at least, Dolichoderus HNS , Monacis HNS , and Hypoclinea HNS appear distinct as good genera. The Indo-Australian forms probably can be split into several good genera along approximately the present subgeneric lines. The best provisional treatment would be that of according generic rank to all present subgenera. Dolichoderus HNS (s. str.) appears the most distinct of all these groups and possibly the most primitive. Specialists in the Indo-Australian fauna can best decide for the present what the status of their part of the fauna is to be, but it does not seem logical to involve any of the Old World forms with any group occurring in the New World except Hypoclinea HNS .

Dolichoderus

Dolichoderus is a genus of ants found worldwide.

Taxonomy[edit]

The ants of the Neotropical genus Monacis were revised in 1959 by Kempf. However, Brown in 1973 and G. C. Wheeler and J. Wheeler in 1973 and 1976 considered both Monacis and Hypoclinea to be junior synonyms of Dolichoderus.[2]

Description[edit]

The type species is Dolichoderus attelaboides. Worker ants in this genus have a body length that is typically about four millimetres and can be recognised by their thick, inflexible and strongly sculptured integument. There is a flange on the underside of the head near the base of the mandibles which is saw-like in some species. The longitudinal suture in the central plate of the metathorax is deeply impressed. The propodeum or first abdominal segment has the posterior face distinctly concave when viewed from the side.[3] The gaster and alitrunk are separated by a single segment, the petiole. The orifice of the cloaca is a horizontal slit rather than a circular opening. It is surrounded by a few rather stiff erect bristles.[4]

Distribution[edit]

Members of this genus are found worldwide, in all the continents except Antarctica.[3]

Biology[edit]

Colonies are of varying sizes and are constructed in the soil, in curled leaves, in the hollow stems of plants and in cartons which are formed by the ants chewing wood and mixing the product with secretions in a similar way to that used by wasps to build their nests. Some species are very versatile with Dolichoderus pustulatus nesting underground in northern parts of the United States while living wholly in trees in the south.[4] The workers seek out and tend sap-sucking insects such as aphids and scale insects that excrete honeydew and they also feed on small arthropods. Some species emit a pungent smelling fluid. Two species, Dolichoderus plagiatus and Dolichoderus taschenbergi, are believed to be polygynous with several queens in one nest. It is also possible that D. taschenbergi may be a temporary social parasite with D. plagiatus as host.[3]

Species[edit]

There are about one hundred and forty recognised species:[5]
